V Fig. 6 is a side view of the improv d line s ep In the usual operation of the slug casting machine, which is partly shown in the drawings, matrices and spacebands are delivered from their places of storage in the machine by the manipu lation of a keyboard (not shown) andare'com posed in line in the usual manner in an assem bling elevator II].

thereupon transfers the line through an intermediate line delivery channel I4 intoa vertically movable line transporter or first elevator I5. As the delivery slide I3 banks against a fixed stop screw I6, which limits the movement of its active stroke, the composed'line will be located in the transporter I5 as indicated by the "dotted lines in Fig. l, where it is restrained against endwise displacement by a yielding line stop I! and a pair of resilient pawls (not shown). The yielding line stop, except for changes subsequently to be described, comprises, as usual ,'a pair of L-shaped slide bars I8 and I9 which are connected together at one end by a connecting memfloer 20 and these slide bars, which extend in parallelism, are spaced to slide in frictional engagement in L-shaped matrix supporting channels 2| and 22 in the front and back jaws 23 and 24 respectively of the line transporter I5. These slide bars extend into the line transporter from the left hand side thereof and their right hand ends form abutments against which the leading or foremost matrix in the line abuts when the line is positioned in the line transporter. The resilient pawls are permanently located at the receiving end of the transporter I5 and they are adapted and arranged to grip or snap in behind the last or terminal matrix as the line comes to rest. After the composed line has been transferred therein the line transporter I5 descends to the casting position where the composed line is positioned between a'pair of vise jaws 25 and 26 which are aligned with the end walls of the mold slot and give to the line the required endwise support during the casting operation. After the slug is cast, the pressure on the vise jaws 25 and 26 is released and the line transporter I5 rises to its line transfer position, the line stop and the pawls meanwhile acting to prevent displacement of the matrices at the opposite ends of the line. As the line transporter I5 reaches its line transfer position, a reciprocatory line transfer slide 21 positioned in a guide 28 in the machine frame operates under the influence of a line transfer slide lever 29 to remove the line from the line transporter I5 to the usual intermediate line transfer channel 36 from which the matrices are removed and conveyed to the matrix distributing mechanism which returns them to their usual place of storage and through which the spacebands are carried by the space band pawl 3| to their usual place of storage. After removal of the line from the line transporter I5 the latter descends in the usual manner to its normal or line receiving position.

In the usual operation of the machine, as described above, it is generally, sufficient that the line stop I! engage the leading or foremost matrix in the line in the ordinary way, the operator in such case usually pushing the line stop I1 inwardly until the right hand ends of the slide bars I8 and I9 engage the leading or foremost matrix in the first line of the measure for which the machine is set and the stop ordinarily remaining in this position, due to its frictional engagement with the walls of the transporter, until I the vise jaws 25 and 26 are reset for a line of a different measure at which time the line stop is again pushed into engagement with the leading ,jor foremost matrix in the first line of the new After the line has been comy. posed therein, the assembling elevator I0 is raised' to position the line between .a pair of depending fingers II and I2 of a line delivery slide I3, which measure. In other classes of Work, however, involving the use of quadding devices, such as those disclosed in U. S. Letters Patent to F. C.

'Frolander No. 1,949,302 wherein the right hand vise jaw 25 is moved inwardly from its normal line receiving position toward the left hand vise jaw 26 to confine the composed line which is shorter than the distance between the jaws for which the machine is set, it is common practice to returnthe line stop I! to the right adjacent the line retaining pawls each time a composed line is transferred from the line transporter I5 to insure support for the leading or foremost matrix in the line thereafter assembled regardless of its length. In the event the line thereafter assembled is short of the measure for which I machines, however, the closing movement of the I5 in supporting relationship with the-'- right hand jaw 25 and the consequent shift of the composed line to the left is sudden and unless means are provided to prevent it the line stop II, when the composed line is suddenly brought to a halt against the left hand vise jaw 26, is quite likely to be propelled beyond its supporting relationship with the leading or foremost matrix in the line, even to the extent of being carried over the left hand vise clamping stud 32 where it would be ruined by the latter when the line transporter I5 descended to casting position.

In accordance with the present invention pro-" pulsion of the line stop beyond its supporting relationship with the leading'or foremost matrix in the line as the line is moved against the'left hand jaw 26 under the influence of the right hand jaw 25 is prevented by increasing the frictional resistance to movement of the line stop I! in the line transporter I5, and to this end a plurality of resilient members are adapted and arranged to press the slide bars IB and I9 of the line stop I! into frictional engagement with the' L-shaped matrix grooves 2| and 22 in the line transporter I5 in a direction other than horizontal to its line of travel in the line transporter.

In the embodiment of the invention illustrated bars until their side faces frictionally engage the epairers to prevent the line stop II from being propelled moved to the left by the closin'g 'movement of: the right hand jaw 25. 1

. The right hand end of the inner slide bar l8 of *the improved l-ine stop is also provided with a stud 36 which is adapted and arranged toengage a stop member 31 positioned at the left hand end of the space band slide groove 38 in the back Ii -shaped slide -bars; and friction 'creating springs fixedly secured to the horizontallyiadismatrices; a line stop-positioned in' the transporter jaw 24 of the line transporter l when the line.

stop I1 is moved to the left a predetermined distance, this arrangement being provided to prevent the line stop I! from beingmoved accidentally to the left to a position where it would engage the left hand vise clamping stud 32 during its travel to or from the casting position.

After the casting operation, the line transporter l5 moves upwardly to its line transfer position where the line is transferred, as usual, to the intermediate line transfer channel 30, and to insure the return of the improved line stop to the right the line transfer slide 21 is provided with a plate 39 having a finger 40 which extends outwardly therefrom and which is adapted and arranged to engage the left hand end of the line stop I! when it is moved to the right in the usual with a stop pin 42 which extends downwardly therefrom and which engages the connecting member 20 when the line stop I! has been moved to this position.

While the improved line stop has been described as being of particular advantage in connection with slug casting machines equipped with quadding and centering devices it is evident that it is also of advantage in connection with machines not so equipped, since it eliminates any possibility of the line stop from being jarred out of supporting relationship with the leading or foremost matrix in the line when the line is left hanging in the jaws of the transporter while the transporter ascends from the line casting to the line transfer position.

Also, it is to be understood that the invention has been shown merely in preferred form and that many changes and variations may be made therein and in its mode of operation which will still be comprised within its spirit. In consequence, the invention is not to be limited to any specific form or embodiment except insofar as such limitations are specified in the claims.
